The shadow under the second "peg" from right is truncated--presumably where you separated it from the lettering below. The hanging objects should also have shadows on the wood.

One thing on the shadows. Just look at how the shadows are on the source picture. They aren't completely black. The light source is fairly harsh, so most shadows should be sharper. Think about where the light is, and where the objects would block it.

Shadows are tough. The more of them you create, the better you will get. The shadows in your update are an improvement. Read ledirlo's shadow tutorial. Examine good shadows by other choppers. You'll get there. :)
